The fixed slat 20 is located above the conveyor belt 10 and is spaced apart from the conveyor belt 10, and is slidably installed on the slot 13 so that the fixed slat 20 can be along the slot 13 To achieve lifting. The fixed slat 20 is made of conductive material, such as metal material. The length and width of the fixed slats 20 can be designed freely. Preferably, the length of the fixed slat 20 may be slightly shorter than the width of the conveyor belt cover 11 by 5 mm, and the width of the fixed slat 20 is 2 dm. The two opposite ends of the fixed slat 20 are respectively provided with a clamping block 21. The clamping block 21 is clamped in the clamping slot 13, so that the fixed slats 20 can slide up and down along the clamping slot 13 to achieve lifting. The relative height of the fixed slat 20 and the conveyor belt 10 can be controlled by sliding the block 21 and the slot 13 relatively.

In this embodiment, the fiber conductive wire 30 includes a first end portion 31 and a second end portion 32 that are disposed oppositely. The first end portion 31 of the fiber conductive wire 30 can be fixed to On the fixed slat 20, the second end 32 protrudes toward the conveyor belt 10. The first The length of the two end portions 32 can be adjusted by adjusting the relative height of the fixed slats 20 and the conveyor belt 10. In this embodiment, the fiber conductive wire 30 naturally sags, and the second end 32 has a gap (not shown) with the conveyor belt 10, and the gap can be adjusted according to the height of the workpiece 60. Specifically, the height of the second end portion 32 is adjusted to contact the surface of the workpiece 60 when the workpiece 60 flows through. In this way, after the second end 32 of the fiber conductive wire 30 is brushed over the workpiece 60 on the conveyor belt 10, the static elimination on the workpiece 60 can be maintained for 3-5 minutes. The spray booth environment varies.
